LFP 4lb pulley

[DET_SVT02]

What I need to know is whats a fair guess as to the gains from a 4lb lower w/SCT tune from LFP as far as RWHP AND TORQUE on a stock truck w/only those mods and a ftvb . If anyone has this setup chime in please.

hmm.... around 390rwhp and 485rwtq i'd say

A buddy of mine with the 4lber, SCT and longtubes just hit 419 - 520

long tubes will give you alot more trq.... my guess is based on seeing other L's on the dyno. my 6# lower and predator tune made 401/503 on stock motor

How about if you add a ported blower to this combo?
